NOTES AND NEW SPECIES OF MICROLEPIDOPTERA FROM WASHINGTON STATE

By J. F. Gates Clarke

In 1933, under the above title, I started a series of papers in which I proposed to deal with the microlepidopterous fauna of the State of Washington. Three of these papers have been published.^ This paper, the fourth, contains descriptions of nine new species and one new genus, as well as notes on other miscellaneous species. In addition, four European species are recorded as new to North America. The drawings for this paper were made by Arthur D. Cushman, staff artist. Bureau of Entomology and Plant Quarantine.

Family GELECHIIDAE

ANACAMPSIS POPULELLA (Clerck)

Phalaena populella Clerck, Icones Insectorum, pi. 11, fig. 5, 1760.

E. I. Smith, Bureau of Entomology and Plant Quarantine, Seattle, Wash., submitted a series of this species for determination. Accom- panying the moths was a series of larvae and pupae. The larvae were collected on a species of Salix and the moths were reared from them. This appears to be the first record of the occurrence of this European species in North America. All specimens are in the United States National Museum.

GNORIMOSCHEMA ARNICELLA, new species

Plate 29, Figures 6, 6a ; Plate 32, Figxire 14

Antenna sordid white anniilated with blackish fuscous. Labial palpus sordid white shaded with gray on inner side of second segment, and irrorated with fuscous outwardly. Head, thorax, and fore wing pale cinereous, lightly shaded with pale brown and profusely, but finely, irrorated with fuscous. On the wing there are five blackish-fuscous spots, one at base of wing just inside costa, one on inner margin slightly farther out, one at one-third between lb and the cell, another between the bases of 9 and 10, and a larger lunate spot at end of cell; cilia ochreous white strongly irrorated with blackish fuscous. Hind wing light gray, darker apically; cilia pale yellowish fuscous. Legs pale cinereous irrorated with fuscous. Ab- domen cinereous, paler beneath. Male genitalm.—Upper arm of harpe almost straight, nearly as long as uncus and tegumen combined; lower arm short, stout. An- terior process of vinculum about as long as lower arm of harpe. Gnathos a rather weak hook. Uncus well developed, rounded. Aedeagus stout, moderately dilated basally, distally with a dorsal protuberance. Female genitalia.—Genital plate broad; ostium heart-shaped. Bursa copulatrix pear-shaped with a strong, slightly curved signum. Ductus bursae short, broad, with a narrow sclerotized ring before the ostium; inception of ductus seminalis at anterior edge of the sclerotized ring. Alar expanse, 14—15 mm. Type.—U.S.'NM. No. 56268. Type locality.—Kamiack Butte, Wliitman County, Wash., 3,000 feet. Food plant.—Arnica cordifolia Hook. Remarks.—Described from the type female (19-V-34, J. F. G. Clarke

No. 5668) ; one female paratype, Newman Lake, Spokane County,

Wash. (July 1915, G. K. Jennings) ; and one male paratype, Shasta Retreat, Siskiyou County, Calif. (August 16-23). One paratype is in the Carnegie Museum, Pittsburgh, Pa.; the other paratype is in the United States National Museum. The larva of this species is a leaf roller on the food plant.

LITA PRINCEPS (Busck), new combination

Gnorhnoschema princeps Busck, Proc. Ent. Soc. Washington, vol. 11, p. 175, 1909.

The type of this species is in the United States National Museum. Although it is in poor condition, consisting of a fore and a hind wing, head without palpi, and two legs, it is easily recognizable as being a

member of the genus Lita Treitschke. Vein 2 of the forewing is remote

from 3, a character that distinguishes Lita from Gnorimoschema Busck. IVnCROLEPIDOPTERA FROM WASHINGTON STATE—CLARKE 269

In addition to the type, I have before me a series of eight specimens from Washington and Utah as follows: Washington: Pullman (23-

IX-1925, J. F. G. Clarke) ; Wenatchee, 5 S $ (23-29-VIII-1929, A. Spuler). Utah: Eureka, $ (27-VIII-1911) and Stockton, 6 (29- VIII-1904), both collected by Tom Spalding. The venation of the Washington and Utah specimens agrees with the type, and the genitalia definitely place these specimens in Lita. In his paper on the restriction of the genus Gelechia ^ Busck re- tained this species in the genus Gnoriinoschema. He undoubtedly did this, despite the obviousness of the venation, because of the inade- quacy of the material before him.

ARLA, new genus

This genus is similar to Lita but differs from it in the extremely long antenna (thickened in the male), the long scaling from the uncus, the armed aedeagus, and the single weak signum. Genotype.—Aria tenuicornis, new species.

BATIA LUNARIS (Haworth)

Recurvaria lunaris Haworth, Lepidoptera Britannica, pt. 4, p. 556, 1829. In the course of making identifications of moths associated with studies on the Dutch elm disease, the apparent similarity between English specimens of Batia limaris (Haworth) and a series of two males and three females from the State of Washington was noted. Further investigation and a comparison of the male genitalia of these with the English specimens and other European material proved them to be identical. MICROLEPIDOPTERA FROM WASHINGTON STATE—CLARKE 275

The Washington specimens were collected at Bonneville and Van- couver, Clark County, from June 26 to July 7, 1931, by the author.

This is the first record of the occurrence of this species in North America although probably it has been in the vicinity of Vancouver since the early settlement of the English on the Columbia River.

Family GLYPHIPTERYGIDAE

ANTHOPHILA PARIANA (Clerck)

Phalaena Tortrix pariana Clebck, Icones Insectorum, pi. 10, fig. 9, 1759. Among material submitted for determination by C. F. Doucette, Sumner, Wash., was a large series of Anthophila pariana (Clerck). This species was formerly placed in the genus Hemerophila. The first record of its occurrence in North America was published by E. P. Felt ^ under the title "Apple and Thorn Skeletonizer." In that paper the insect was listed from several localities in New York State. In the United States National Museum there are specimens from Con- necticut, Rhode Island, New Jersey, and New York, but those received from Mr. Doucette from Washington represent the first known record of the occurrence of A. pariana in the western part of the United States.

Tinea pyrella Viixebs, Caroli Linuaei Entomologia, Faunae Suecicae descrip-

tionibus aucta, vol. 2, p. 515, 1789.

In the course of making identifications of moths from Washington State, the study of the genitalia of a pair of Microlepidoptera from Bellingham proved them to be the European Sioamnierdamia pyrella (Villers), not previously recorded from North America. These moths were collected August 13, 1932, by the author. The larva feeds on the leaves of apple and prune.

ERIOCRANIA SEMIPURPURELLA (Stephens)

Lampronia semipurpurella Stbthens, Illustrations of British Entomology,

Before me is a series of four moths of this species collected at Bellingham (3-8-IV-1923, J. F. G. Clarke No. 3709-12) at light. Although these were collected many years ago, it has become pos- sible to identify them only recently and to record the presence of this European species in North America for the first time. When the above specimens were collected, the species was abundant at light. I have not seen it since. VOL. 92 PLATE 27 U. S. NATIONAL MUSEUM PROCEEDINGS,
